chore(docs): Add CSF examples

[benmvp]

Problem

I had two problems:

1. I was unsure if I had to install @storybook/addon-knobs with storybook-addon-smart-knobs
2. The examples were not in Component Story Format so I wasn't sure what the equivalent CSF code looked like. Once I did, I was also unsure what order the decorators should go in.

Solution

I updated the installation instructions to include @storybook/addon-knobs for extra clarity.

The main part was adding examples for CSF. I have some set of stories that display the component multiple times in a story, so including the decorator globally messed up those stories because it was passing the same parameters into all of the components. So I added an example of adding the decorator at the story level.

Notes

I also added a fix for what I believe was a bug in the ignoreProps options example.
